Trailer Bearing 14125A for 7,000 and 8,000lb (8 Lug) Trailer Axles, 1 1/4" ID

This tapered trailer roller bearing is standard bearing number 14125A, measuring 1 1/4 inch inner diameter and fitting into race #14276.  This is a Tapered Roller-Style Bearing, which is the most common bearing type among Trailer Hubs. This bearing is most commonly seen in axles that are 7,000-8,000 lb capacity with 8 lug hubs, where this is used as the outer bearing. This is generally going to be the smaller bearing of an 8 bolt hub's bearing combination, used in conjunction with a 25580 bearing to fit onto a tapered 1 3/4" x 1 1/4" trailer spindle. It is certainly one of the more common outer bearings for heavy-duty 7k and 8k hubs, but it's always best to check your Trailer Hubs and Axle to make sure you get a proper Bearing replacement for your Boat or Utility Trailer.
